Description

Technical Field

[0001] This invention relates to the field of filtration and dust removal equipment technology, and in particular to a high-efficiency activated carbon filtration and dust removal equipment for chemical tail gas. Background Technology

[0002] In the chemical industry, a large amount of complex exhaust gas is generated during production. This exhaust gas contains not only particulate matter and various volatile organic pollutants, but also often highly viscous impurities such as tar and resin aerosols. If these harmful pollutants are not effectively treated and are directly emitted, they will cause serious pollution to the atmospheric environment and threaten the health of the surrounding population. Therefore, efficient and stable exhaust gas purification has become an indispensable part of the chemical production process. Activated carbon, with its well-developed pore structure, huge specific surface area and excellent adsorption performance, is widely used in the filtration, dust removal and deep purification of chemical exhaust gas. However, during the long-term application of activated carbon, viscous substances such as tar carried in chemical exhaust gas will continuously come into contact with and act on the activated carbon layer with the airflow. The viscous tar components will block the microporous channels inside the activated carbon on the one hand, and cover the effective adsorption surface of the activated carbon on the other hand, directly leading to a significant reduction in the effective adsorption sites of the activated carbon, reducing the purification effect of the activated carbon layer on exhaust gas and its service life. To address these issues, we propose a high-efficiency activated carbon filtration and dust removal device for chemical exhaust gas. Summary of the Invention

[0016] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0017] Reference Figures 1-14 A high-efficiency activated carbon filtration and dust removal device for chemical tail gas includes a main body 1, with an air inlet pipe 2 fixedly connected to the left end of the main body 1 (refer to the left end here). Figure 1 , Figure 1 The intake pipe 2 is located at the left end. An activated carbon layer 3 is fixedly installed on the inner wall of the main body 1 in a linear and uniform manner. An energy storage component 6 is installed inside the intake pipe 2, and a filter component 9 is installed inside the main body 1.

[0018] The power storage component 6 includes a fixed plate 61 fixedly installed on the inner wall of the intake pipe 2, a threaded rod 63 rotatably installed on the fixed plate 61, a slip ring 65 threadedly installed on the threaded rod 63, a disc 66 rotatably installed on the slip ring 65, a cleaning component installed on the disc 66, and a power storage component installed on the threaded rod 63.

[0019] The power storage component includes ventilation holes 62 that are evenly distributed in a ring on the fixed plate 61, and all ventilation holes 62 are inclined. A wind turbine 64 is fixedly installed on the threaded rod 63, and two telescopic rods 67 are fixedly installed between the wind turbine 64 and the disc 66.

[0020] When the chemical exhaust gas is introduced into the intake pipe 2 and flows continuously to the right through multiple inclined ventilation holes 62 (along... Figure 3 (As shown in the direction), the force exerted by the flowing exhaust gas on the blades of the wind turbine 64 drives the wind turbine 64 to rotate. When the wind turbine 64 rotates under force, through its cooperation with the threaded rod 63, the slip ring 65, and the two telescopic rods 67, it can drive the disc 66 to move to the right (along the direction shown in the figure). Figure 7 (as shown in the direction), and at the same time, through the cooperation of the impeller 64 and the two telescopic rods 67, the rotational torque transmitted to the disc 66 can make the disc 66 rotate synchronously during the rightward movement. In the process of the disc 66 being subjected to force and rotating displacement, the torsional storage and axial compression of the torsion spring 7 can be completed simultaneously.

[0021] Reference Figure 2 , Figures 8-11 The filter assembly 9 includes a partition 5 fixedly installed on the inner wall of the main body 1. A torsion spring 7 is fixedly installed between the partition 5 and the disc 66. A compression spring 916 is fixedly installed on the partition 5. A plate 914 is fixedly installed on the compression spring 916. An elastic membrane 917 is fixedly installed between the plate 914 and the partition 5. A gas collecting cylinder 96 is clamped and sealed and rotatably installed on the plate 914. A condensation mechanism is installed on the gas collecting cylinder 96 for pre-condensation and removal of viscous substances such as tar in chemical exhaust gas. A scraping mechanism is installed on the gas collecting cylinder 96.

[0022] The condensation mechanism includes a liquid storage tank 91 fixedly installed on the main body 1 of the device. A cooler 92 (a conventional product whose structure and working principle are not part of the improvements in this solution, and therefore will not be described in detail here) is installed on the liquid storage tank 91. A liquid delivery pipe 93 is fixedly connected to the cooler 92, and the liquid delivery pipe 93 is sealed through and fixedly installed on the main body 1 of the device. A circular ring 95 is fixedly connected to the telescopic end of the liquid delivery pipe 93, and the circular ring 95 is sealed and engaged with the gas collecting cylinder 96. A box (shown in the figure but not labeled, from...) is fixedly installed at the lower end of the main body 1. Figure 11As can be seen from the image, a drain pipe 94 is fixedly connected between the ring 95 and the box body, and the drain pipe 94 is sealed and fixedly installed on the main body 1 of the device. A return pipe is fixedly connected between the box body and the storage tank 91. A liquid delivery component is installed between the ring 95 and the gas collecting cylinder 96 (in conjunction with...). Figure 9 It can be seen that the purpose of connecting the telescopic ends of the infusion tube 93 and the drain tube 94 to the ring 95 is that when the subsequent gas collecting cylinder 96 is subjected to force and drives the ring 95 to move, the ring 95 can always be connected to the infusion tube 93 and the drain tube 94 by stretching or compressing the telescopic ends of the infusion tube 93 and the drain tube 94. Furthermore, by using the cooperation of the infusion tube 93 and the drain tube 94 to limit the position of the ring 95, it can be ensured that the ring 95 will not rotate synchronously with the gas collecting cylinder 96.

[0023] The infusion component includes a liquid collection groove 97 formed on a ring 95, a drain groove 98 formed on the ring 95, and square openings 99 evenly distributed in a ring on the gas collecting cylinder 96.

[0024] When the chemical exhaust gas to be filtered is introduced into the main body 1 of the device, the water pumps inside the cooler 92 and the storage tank 91 are started first (the water pumps are existing conventional products, and their structure and working principle are not part of the improvement of this solution, so they are not shown in the accompanying drawings). The operation of the cooler 92 will draw the liquid stored in the storage tank 91 into its interior, and after cooling the liquid to a suitable temperature, it will be introduced into the delivery pipe 93. Subsequently, this part of the liquid will flow along the wall of the delivery pipe 93 and flow into the liquid collection tank 97 opened on the annulus 95, and finally flow into the middle interlayer of the gas collecting cylinder 96 through the square opening 99 corresponding to the position of the liquid collection tank 97 (in conjunction with...). Figure 10 and Figure 11 (It can be seen that...)

[0025] The gas collecting cylinder 96 is constructed entirely of metal materials with excellent thermal conductivity, such as aluminum alloy, stainless steel, and copper alloy. Utilizing the high thermal conductivity of this material, when cryogenic liquid flows into the intermediate interlayer of the gas collecting cylinder 96, and chemical exhaust gas enters the cylinder, the cryogenic liquid in the intermediate interlayer can exchange heat with the high-temperature exhaust gas inside the cylinder through the cylinder wall. (In the chemical industry, processes such as exothermic synthesis reactions, material distillation and evaporation, and high-temperature incineration carry a large amount of waste gas.) Due to the residual heat from the process, the exhaust gas temperature is generally high. This process cools the high-temperature exhaust gas. During the cooling process, high-boiling-point viscous components such as gaseous tar and resin aerosols carried in the exhaust gas can be removed by pre-condensation. This effectively prevents the viscous impurities such as tar carried in the exhaust gas from blocking the adsorption pores of the activated carbon layer 3. This helps to ensure the long-term stability of the adsorption capacity and flow performance of the activated carbon layer 3, and improves its continuous filtration and purification effect on the chemical exhaust gas.

[0026] Simultaneously, when the cooled liquid enters the intermediate interlayer of the gas collecting cylinder 96 and continues to flow along the interlayer wall to the position of the square opening 99 at the lower end of the gas collecting cylinder 96 (along... Figure 13 (As shown in the direction), the liquid will flow into the drain trough 98 opened on the ring 95 under its own gravity, and eventually collect in the box along the wall of the drain trough 98 and the wall of the drain pipe 94. At this time, by operating the water pump installed in the storage tank 91, the liquid inside the box can be pumped back into the storage tank 91 through the return pipe, so as to facilitate the subsequent recycling of this part of the liquid. This can not only ensure the heat exchange effect and efficiency of the low temperature liquid and the exhaust gas in the gas collecting cylinder 96 jacket, but also improve the utilization rate of liquid resources.

[0027] Reference Figures 2-14 The disc 66 is fixedly installed with a ring-shaped and evenly distributed clamping rod 610, and the gas collecting cylinder 96 is provided with a ring-shaped and evenly distributed groove, and two elastic plates 915 are fixedly installed on each groove.

[0028] The scraping mechanism includes a flow equalization plate 4 fixedly installed on the inner wall of the main body 1 of the device. A round rod 910 is fixedly installed on the flow equalization plate 4, and the round rod 910 is sealed through and slidably installed on the air collecting cylinder 96. Scrapers 911 evenly distributed in a ring are fixedly installed on the round rod 910, and an air collecting component is installed on the air collecting cylinder 96.

[0029] The gas-gathering component includes an exhaust pipe 912 that is uniformly and annularly fixed and connected to the gas-collecting cylinder 96, and a one-way valve 913 is installed on each exhaust pipe 912.

[0030] The cleaning components include a push ring 68 that is snapped onto a disc 66, two scraper brackets 69 that are fixedly mounted on the push ring 68, and both scraper brackets 69 are sealed through and slidably mounted on the partition 5, and the right ends of both scraper brackets 69 are sealed and slidably mounted on the inner wall of the device body 1, and two collection boxes 8 are sealed through and fixedly mounted on the device body 1.

[0031] Each of the multiple one-way valves 913 consists of a baffle, a return spring, and a rotating rod. Each rotating rod is rotatably mounted on a corresponding exhaust pipe 912, and each baffle is fixedly mounted on a corresponding rotating rod. Each baffle and its corresponding exhaust pipe 912 is fixedly fitted with a return spring. In the initial state, because the exhaust gas flow rate entering the gas collecting cylinder 96 is small, the thrust of the airflow on the baffle in the one-way valve 913 is less than the preload force of the return spring. Therefore, at this stage, all one-way valves 913 inside the exhaust pipe 912 are in a closed state.

[0032] When the wind turbine 64 is driven by force, the disc 66 and the multiple levers 610 on it continue to move to the right (in combination with...) Figure 7 and Figure 8As shown in the direction, when multiple levers 610 rotate to face the corresponding grooves and gradually insert into the grooves, the squeezing force applied by the ball at the end of the lever 610 to the two elastic plates 915 in the corresponding grooves will push the two elastic plates 915 away from each other until the ball at the end of the lever 610 is in contact with the bottom wall of the corresponding groove. At this time, the rebound clamping force applied by the two elastic plates 915 to the lever 610 can achieve relative locking between the two elastic plates 915 and the corresponding lever 610, thereby achieving fixed linkage between the disc 66 and the air collecting cylinder 96. At this time, the air collecting cylinder 96 can rotate and move together with the disc 66.

[0033] Furthermore, due to the limitations of the tilt angle of the ventilation hole 62 and the tilt angle of the blades on the impeller 64, the force exerted by the exhaust gas flow on the impeller 64 can only drive the impeller 64 and the threaded rod 63 to rotate in the forward direction. When the exhaust gas passes through the impeller 64 and engages with the threaded rod 63 and the slip ring 65, driving the disk 66 to move to the rightmost end of the threaded rod 63 (along... Figure 2 (As shown in the direction), constrained by the travel limit at the end of the threaded section on the threaded rod 63, the rotation of the threaded rod 63 cannot drive the disc 66 to continue moving to the right. At this time, the elastic potential energy is released through the torsion spring 7, which can quickly drive the disc 66 and the air collecting cylinder 96 to rotate in opposite directions. When the disc 66 is rotated in the opposite direction under force, the reverse force applied to the wind turbine 64 by the two telescopic rods 67 can drive the wind turbine 64 and the threaded rod 63 to rotate in opposite directions. At this time, through the cooperation of the threaded rod 63 and the slip ring 65, the disc 66 can be driven to move quickly to the left to reset during the process of being rotated in the opposite direction under force (along the direction shown in ... Figure 4 direction shown).

[0034] At the same time, during the process of the gas collecting cylinder 96 rapidly rotating and shifting to the left due to the force exerted on the disc 66 (such as... Figure 10 (As shown in the direction), the exhaust gas inside the gas collecting cylinder 96 will simultaneously form a high-speed swirling flow. At this time, by utilizing the density difference between the gaseous exhaust gas and viscous particles such as liquid tar, the denser liquid tar component can be thrown towards the inner wall of the gas collecting cylinder 96 under the continuous centrifugal force. This achieves the separation of the gaseous exhaust gas and viscous substances such as liquid tar. Furthermore, during the process of the gas collecting cylinder 96 rotating and moving to the left under force (along the direction shown in the figure), the exhaust gas will be separated from the viscous substances such as liquid tar. Figure 11 As shown in the direction, through the cooperation of multiple scrapers 911, viscous substances such as liquid tar adhering to the inside of the gas collecting cylinder 96 can be scraped off, and the scraped viscous substances such as tar can be pushed to the right and finally collected on the right side of the gas collecting cylinder 96. In this way, the condensation mechanism can be used to continuously condense and remove impurities from the exhaust gas entering the gas collecting cylinder 96, and ensure that the device can continuously remove viscous substances such as tar from the chemical exhaust gas.

[0035] As the amount of exhaust gas collected inside the gas collecting cylinder 96 gradually increases and the internal air pressure gradually rises, when the thrust of the gas acting on the baffle of the one-way valve 913 exceeds the preload of the corresponding return spring, the exhaust gas collected in the gas collecting cylinder 96 will push the one-way valve 913 to open (i.e., push the corresponding baffle and the rotating rod to deflect synchronously), and spray out from the corresponding exhaust pipe 912. At the moment when the one-way valve 913 is opened, a significant pressure difference will be formed between the high-pressure gas inside the gas collecting cylinder 96 and the outside of the exhaust pipe 912. After the exhaust gas is throttled and accelerated through the narrow flow section of the exhaust pipe 912, it will be sprayed out at high speed.

[0036] When the high-speed flowing exhaust gas collides with the inner wall of the main body 1 of the device, the density and mass of the viscous substances such as liquid tar carried in the exhaust gas are much greater than those of the gas phase components, and they have stronger inertia. They cannot change direction synchronously with the gas phase exhaust gas. Therefore, the viscous substances such as liquid tar will be driven by inertial force to leave the gas phase flow field, realizing the separation of the gas phase exhaust gas and viscous substances such as tar. This can help improve the pre-removal effect of the device on viscous substances such as tar in the exhaust gas, thereby ensuring the continuous and efficient filtration effect of the subsequent activated carbon layer 3 on the chemical exhaust gas.

[0037] Furthermore, when multiple one-way valves 913 are opened, the centrifugal force generated by the high-speed rotation of the gas collecting cylinder 96 can throw out viscous substances such as liquid tar that have gathered at the right end of the gas collecting cylinder 96, so as to ensure the condensation and impurity removal effect of the exhaust gas inside the gas collecting cylinder 96 through the condensation mechanism. The viscous substances such as liquid tar that have been thrown out will fall onto the inner wall of the main body 1 of the device under their own gravity.

[0038] Meanwhile, the high-speed flowing gas phase exhaust gas will quickly turn along the inner wall of the device body 1 after contacting the inner wall flow channel and continue to flow to the right. At this time, the flow equalization plate 4 can, to a certain extent, rectify and homogenize the exhaust gas, disperse the locally concentrated airflow and spread it evenly to the entire internal cross section of the device body 1, thereby improving the uniformity of contact between the exhaust gas and the activated carbon layer 3, avoiding the problems of local airflow concentration and uneven filter material load, and helping to improve the filtration effect of the activated carbon layer 3 on the overall exhaust gas to a certain extent.

[0039] When the disc 66 is subjected to force, the gas collecting cylinder 96 continues to rotate and shift to the left (in combination with...). Figure 8 and Figure 11(As shown in the direction) When the right end of the gas collecting cylinder 96 contacts multiple scrapers 911, the moving resistance applied to the gas collecting cylinder 96 by the round rod 910 and multiple scrapers 911 allows multiple locking rods 610 on the disc 66 to gradually move out of the corresponding grooves. After the disc 66 separates from the gas collecting cylinder 96, the elastic potential energy released by the torsion spring 7 continuously drives the disc 66 to move and reset. Repeating the above operation steps can achieve continuous pre-removal of viscous substances such as tar in the exhaust gas, and improve the continuous filtration of chemical exhaust gas by multiple activated carbon layers 3.

[0040] At the same time, when the gas collecting cylinder 96 is subjected to force and rotates and moves left and right (along...) Figure 14 (As shown in the direction), the plate 914 will move together with the gas collecting cylinder 96 by compressing or stretching the elastic membrane 917, thereby ensuring that the exhaust gas entering the left end of the partition 5 (along the direction shown in the figure) Figure 3 (As shown in the direction) All will enter the gas collecting cylinder 96, and only after the gas collecting cylinder 96 completes condensation and preliminary centrifugal filtration will they flow into the right end of the partition 5 and the interior of the device body 1. This ensures that the device, through the cooperation of the condensation mechanism and the gas collecting cylinder 96, achieves the pre-separation effect of viscous substances such as tar in chemical tail gas.

[0041] At the same time, when the disc 66 is subjected to force, it drives the gas collecting cylinder 96 and the plate 914 to move to the left (along... Figure 14 (In the direction shown), the plate 914 will simultaneously stretch the compression spring 916. When the round rod 910 and multiple scrapers 911 cooperate to prevent the gas collecting cylinder 96 from moving further, under the action of the elastic potential energy released by the compression spring 916, the gas collecting cylinder 96 can quickly move to the right and reset, so as to facilitate the subsequent cooperation of the power storage component 6 and the filter component 9 to pre-remove viscous substances such as tar in the chemical exhaust gas.

[0042] Furthermore, when the force of the flowing exhaust gas interacts with the energy storage component 6 again, it drives the disc 66 to move to the left (in conjunction with...). Figure 4 and Figure 8 As shown in the direction, the disc 66 drives the push ring 68 and the two scraper frames 69 to move synchronously to the right. During this process, the two scraper frames 69 can scrape off the viscous substances such as liquid tar adhering to the inner wall of the device body 1 and push the scraped liquid tar and other viscous substances above the two collection boxes 8. Thereafter, the liquid tar and other viscous substances will flow and collect in the collection box 8 under their own gravity. This can prevent the viscous substances such as tar adhering to the inner wall of the device body 1 from solidifying and clumping due to long-term adhesion and coking, thus avoiding the problem of increased ventilation resistance.

[0043] To further clarify, the aforementioned fixed connection should be interpreted broadly unless otherwise explicitly specified and limited. For example, it may be welding, gluing, or integral molding, or other conventional methods well known to those skilled in the art.

[0044] In this invention, when the exhaust gas is input into the intake pipe 2 and continuously flows into the gas collection cylinder 96 to the right (along... Figure 3 (As shown in the direction), through the cooperation of the cooler 92 and the condensation mechanism, the exhaust gas entering the gas collecting cylinder 96 can be continuously cooled. During the cooling process, high-boiling-point viscous components such as gaseous tar and resin aerosols carried in the exhaust gas will undergo phase change after the exhaust gas temperature drops below its dew point temperature, condensing from gaseous to liquid droplets. This achieves pre-condensation and removal of viscous substances such as tar in chemical exhaust gas. At the same time, through the cooperation of the energy storage component 6 and the filter component 9, the separation of gaseous exhaust gas and liquid viscous substances such as tar can be repeated, which helps to improve the filtration effect of multiple activated carbon layers 3 on chemical exhaust gas and improve the filtration effect of the device on chemical exhaust gas.

[0045] Meanwhile, through the cooperation of the scraping mechanism and the power storage component 6, viscous impurities such as liquid tar adhering to the inner wall of the gas collecting cylinder 96 can be intermittently scraped and cleaned, ensuring that the gas collecting cylinder 96, power storage component 6, and filter component 9 work together to continuously condense and remove viscous substances such as tar in chemical exhaust gas. This can help delay the adsorption saturation cycle of multiple activated carbon layers 3, extend the service life of their filter media, and improve the continuous filtration effect of the device on chemical exhaust gas.

[0046] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
